Wireless Series Devices
MadgeTech’s RF series line of wireless-enabled data loggers provides a
simple, low-cost wireless solution for short-range data collection applications.
These products are powered by a user-replaceable internal battery and can
be configured for up to ten years of battery life. They are designed for oneway, low data-rate applications, and transmit real-time data directly to a PC
for monitoring. Like MadgeTech’s standard series of data loggers, they are
simple to use and their versatile configuration options allow for easy integration into a wide variety of applications. The product line includes models for
all the most popular commercial and industrial measurements, as shown in
this table:
These products have onboard memory in addition to the wireless transmitter,
so they can completely replace existing data loggers and strip chart recorders while providing an added wireless data link. This memory can also serve
as a failsafe backup, in the event of interference in the wireless channel or
interruption of service to the monitoring computer.
Wireless: Transmitter Characteristics
The transmitter used in the RF series products is a carrier present-carrier absent (CPCA) amplitude-modulated (AM) signal operating at a carrier frequency of 418 MHz. The data being transmitted is encoded similarly to standard
RS232 serial data at a bit rate of 4,800 baud. This signal is detected by the
RFC101A receiver module and converted to RS232 signals, which are passed
to the COM port of the monitoring PC.
